* Resynchronise with Debian. Remaining changes:
- Use and depend on the Ubuntu keyring.
- Enable the restricted component by default, unless
apt-setup/restricted is preseeded to false.
- Set up the default sources.list to look in -updates and -security (the
latter from apt-setup/security_host and apt-setup/security_path) as
well as the unadorned suite; also -proposed if apt-setup/proposed is
true.
- Use Ubuntu kernel image names.
- Allow preseeding base-installer/kernel/override-image to force a given
kernel to be used.
- Install busybox-initramfs rather than busybox.
- Revert Joey's patch to call base-installer.d hooks after running
debootstrap, which broke console-setup's expectation of being able to
insert its configuration file into /target before console-setup is
installed by debootstrap.
- Add armhf/keystone, armhf/omap, and armhf/omap4 subarchitectures.
- Install kernel headers to match the kernel. This may be overridden by
setting base-installer/kernel/headers to false.
- Add base-installer/kernel/backports-modules template, which may be
preseeded to install selected linux-backports-modules-* packages.
- Move some kernel installation support code from bootstrap-base to
base-installer, and allow live-installer to override the title
template used by that.
- Add powerpc/e500 and powerpc/e500mc subarchitectures.
- Add overlay archive support.
* Fix up architecture tests to still pass with less delta from Debian.
